Requirements documentation

First of all, I want to thank you for the great requirements guide you have made. It was really necessary to know how to manage requirements with TFS.

Currently on my workplace, we use this large Word Document containing all the requirements, so we don´t have traceability on each one, but only for the full document. We would like to improve this by documenting on the TFS work items, however, wo don´t
know how to "generate" our document for validation with the client when the information is divided among work items, specially if there is a document for every use case.

We would appreciate some guidance in this aspect. Perhaps you could include this recommendations in the general guide.
